Comment 7 for bug 663395

Confirmed here too. I have a dell workstation t5400. Firefox and any other browser and event apt-get will take a while before it resolves the site or IP address. I have checked and make sure it's not my network. In addition i have also checked the resolv.conf but nothing everything is pretty much the same as all the other ubuntu systems I have.
Mind you that i was running 9.04 and did a clean install/update. Everything works except for the Network connectivity it. I am using conky to monitor the stats for my NIC and it shows that Eth0 to be really slow average is 1.5Kib and from time to time it drops completely to 0b or between 9B to 80b ...not even 1K.
I have tried disabling ipv6 using the command above from "Carroarmato0 " no luck ....
